To all whom it may concern:

Be it known that I, ANoELo PERM, a citimen of the United States, residing at Grove land, in the county of Essex and State of lvlasrachusctts, have invented certain new and useful Improvements in Wiping Mechanism, of which the following is a specification, reference being had therein to the so companying drawing.

This invention relates to lasting machines, and more particularly to a novel Wiping mechanism for use in the lasting step in the manufacture of shoes.

In the lasting of shoes a sectional Wooden last is usually employed for givin form to the shoe. The shoe upper is required to be assembled with the sole about the last, as a form, and the lasting process may comprise the steps of first pulling-over the flexible upper about the fore part of the shoe, and thereafter Wiping the extending side margins and the margins at the heel and toe. Such Wiping consists in forcing, smotthing and pressing the overhanging material of the upper into place about the last and inner sole, Where it may be suitably secured preparatory to subsequent operations, including attachment of outer sole. In my prior Patent No. 1,168,963, granted January 18, 1916, I have shown a machine in which all of the above described steps or operations may be performed, the machine comprising a shiftable jack which holds the shoe, a pulling-over mechanism, and heel and toe Wiping mechanisms.

The present invention pertains more especially to a Wiping mechanism adapted to use at the toe end of the shoe, although various features hereof might be effectively otherwise employed; and the principal object of the present improvement is to afford a Wiping mechanism which will be simple and durable in construction, and eflicient and convenient in operation.

The present application, therefore, discloses one form or illustration of a toe wip ing mechanism embodying the present invention. It may be variously employed. For example, the mechanism hereof may be employed in chine in which the inverted shoe is inserted after having been pulled-over and in which usually botli the heel and toe portions of the shoe upper ere wiped and secured. On the other hand, the mechanism hereof may be a so-called bed lasting masubstituted in such a machine as that of said Patent No. 1,168,963 for the toe Wiping mechanism there strewn. Or the mechanism hctcofinlght, in some cases, if desirable, be employed by itself solely for the wiping of toes of shoes.

The toe wiping mechanism herein illustratcd is adapted to be employed in such a combination of pulling-over mechanism, jack and wiping mechanism as is shown in my copendin application Serial No. 132,806, filed November 232, 19 16; and the features of combination and the other mechanisms are not shown or claimed herein, but are made the subject of claim in said eo ending application.

Among the particular objects to which the present invention is directed is to pie vid-s a toe wiping mechanism adapted to efficient and convenient use for the'wiping of both shoes, that is, the right andieft shoes of a pair. A mechanism Which is quickly reversible for this purpose is Very advantageous as permitting the o e ator to complete his Work in both shoes of a fair before operating upon other shees. Ii: is very desirable that a Wiping mechanism .shail be free from the necessity of separate adjusting operations to adapt it for the right and left shoes of a pair. Ordinarily separate wiping plates or blades have been used for the two shoes of a pair, and it is an aim hereof to provide that a single set bf Wipin plates serves both for the right and the le t shoe.

It is a plan and object hereof to so arrange that each of ti. single set of Wiper plates may be reversed for converting it from one side to the other side of the shoe toe contour, To do this I provide that each plate shall be teustructed at different parts of its periphery to adapt it respectively to the contour of both sides of the shoe. By this means the reversal of both plates Without shifting either of them across the longitudinal axis of the machine converts the iping mechanism from one adapted to a right shoe to one adapted to ti leftshee, and vice versa.

By this improvement, when the wiser plat-es have been once adjusted for one shoe, no further adjustment for the other shoe is required. These desirable points constitute objects of the present invention, and further objects. and advantages will be elucidated in the hereinafter following description, or will be apparent to those skilled in the art.

To the attainment of the above referred to objects and advantages the present invention consists in the novel lasting machine or wiping mechanism and the novel features of arrangement, design, combination and detail herein illustrated, described or claimed.

The accompanying two sheets of drawings contain the following figures.

Figure 1 is what may be considered a front elevation of a lasting machine or a wiping mechanism embodying the present invention, the wiper plates standing at the extreme right, and the shoe A being supposed to be held to the right thereof in inverted position and with the toe directed leftward.

Fig. 2 is a top plan view of the machine.

Fig. 3 is a left elevation of certain ad justing parts in Figs. 1 and 2.

Fig. 4 is a central longitudinal section on the plane H of Fig. 2.

Fig. 5 is a detailed plan view on an en larged scale of the wiper plates and their immediately connected mechanism, with the cover plate removed. The set of wiper plates are shown in position for wiping a right shoe.

Fig. 6 is similar to Fig. 5, but with each wiper plate reversed, so as to readapt the wiping mechanism to a left shoe.

Fig. 7 is a top plan view of certain of the underlying parts in Figs. 5 and 6, the majority of the movable parts being omitted.

Fig. 8 is a detached plan view of the gear segments employed for reversing the wiper plates.

Fig. 9 is a detached plan view of the gear segments or carriers by which the plates are swung to move their wiping edges toward and from each other as the wiping device is bodily advanced toward the shoe and retracted.

Above any suitable base may be mounted a longitudinally and vertically adjustable support or post 12, and above this is shown a carriage 13, having a dovetailed engagement with the post to permit transverse adjustment of the wiping mechanism. Upstanding from the carriage 13 are opposite brackets 14. At the top of the brackets are bearings 15 for trunnions 16, between which the entire wiping mechanism or head is supported, thetrunnions permitting swinging adjustment to secure any desired longitudinal incline or tilt.

Before describing the details of the wiping head I will mention the usual or necessary motions, adjustments and operations involved in too wiping. In addition to the longitudinal vertical and transverse adjustments already mentioned, and the longitudiwithin the shell.

nal tilting about the trunnions 16, I have shown means for effecting a lateral incline or tilt of the wiping head. A horizontal swinging adjustment about a convenient ver tical axis to change the direction of wiping action with respect to the shoe may sometimes be employed, but is not herein shown, as it is assumed that the shoe holding jack will be capable of a swinging movement to secure the desired relative adjustment.

Finally, we come to the operative wiping movements of the wiper plates. These movements of the Wiper plates toward and from the shoe are supposed to take place in conjunction with the bodily lifting and lowering movements before mentioned, and subsequcntly to effecting the various adjusting movements previously mentioned. The wip ing movement here n is shown as consist ing of the bodily advance and retraction of the wiper plates in a longitudinal direction accompanied by a swinging or converging movement during the advance, the retreat ing movement of the plates being accompa nied by their separation or swinging apart.

Where the contour of toes diliers extensively the wiper plates must usually be interchanged for other plates of the proper contour. By the present invention, when the pair or set of plates for one shoe are replaced by another pair or set of the proper contour, the interchange is complete and no further interchange is necessary for the mate, since, according to this invention, the same set of plates is made to serve for wip ing both the right and left shoes of a pair.

The movement or shifting or adjustment of the wiper plates hereof to adapt them from one to the other shoe consists herein, as before slated, substantially in a reversal of the position of each plate without reversing its location from one side to the other of the machine; and preferably the reversal is made by a rotation in its own plane substantially about a vertical axis located within the area of the plate. This invcntion comprises means for quickly and conveniently reversing the wiper plates in the manner described to prepare the machine for operation upon rights and lofts.

Generally speaking, the trunnions 16 at the top of the brackets support a cylindrical shell or housing 17, which is hung between them so as to swing about a. transverse horizontal axis to permit adjustment of the longitudinal tilt.

Within the shell 17 is a cylindrical memher. which may be termed a carrier 18. The member 18 is adapted to move in two modes Firstly, it may slightly rotate or oscillate to secure the desired lat eral tilt of the wiping head. Secondly, it may move bodily longitudinally so as to carry the wiper plates toward and from the work during the wiping action. The carrier 1J8, therefore, is the aotively movable member during the wiping; operations. This oarrier has afoas'ward extension; 129, which aflords the support for the wiper plates 20 and 21', and the various fittings asfioeiwted with them, which will be subsequently described.

The near wiper plate- 20 and the far plate 21 are constructed on the some parincip-lkes, but are not identical in drape or contour. As before stated, eaeh of them is adapted to be shifted for the purpose of reversal, and for this purpose each plate is provided with. a: suitably located vertical pivot 22. As shown, each pivot 22 is an interior pivot or axis, being located substantially nee-r to the middle portion of the area of web wiper plazte. By this arrangement each plate, in rotating horizontally to reverse itself, does so Withoutsubstantially ehanging its location in the machine. Eqmivallent rotary or other reversing nwvements might be: employed to the same end.

I do aot attempt to employ the some pEate contour for both shoes of as pair, hut, on the contrary, each Wiper plate isprovided at its periphery with two separate: contour portions adapted respectively to right and left shoes. Thus, as shown in Fig. 5', the Wiper plate 2:0 has a eontonr 23 for a. pos tion of the toe of a. right shoe, and the wiper plate 21 has a cooperating contour 2% ior the opposite side of the toe of the right shoe. Fig. 5;. therefore, shows the position of the plates for wiping a right shoe. When the plates are reversed by a: rotation around the pivots 22, they assume the Fig. 6 position, in which it will be seen that the wiper plate 20 has a contour 25 adapted for one side of the toe of a left shoe, While the Wiper plate 24 has a cooperating contour 26 for the left shoe.

Each of the two Wiper plates is so shaped and fitted with regard to the Wiping con tours and the center of rotation that in either operative position the Wiping may be effectively performed without conflict or obstructions by other portions of the plate. Owing to this advantageooe arrangement, no readjustment whatsoever of the location of the plates is required, or other adjustment with respect to the wiping head, and the simple rotary reversing movem nt described brings about the complete change from the Fig. 5 to the Fig. 6 position to convert the mechanism from right to left shoes.

It will be noticed that the reversing action is one requiring very slight muscular eflort, since praetieelly only the two wiper plates of insignifiozml weight are required to be shifted, and. as will be seen. I have pmvided that the two plates with a single manual movement or adjustment may he simulhinmimly reversed in an ely convenient and expeditious manner. This mere: palate reversing action completely cone veete the machine for wiping rights or lofts, with the; exception of the requirement that the lateral tilt he reversed, and connections may be provided herein such that the throw oi m singlie lover or mmiipn'leting part may simultaneously reverse the Wiper plz tes and also the lateral tilt, if desired li'hieo the wiper plates have been set in either of their opomtive positions, it is desire-hie to lock them in such adiiznetment, so that they may be held e-flectivelly and rigidly with relation to the mechanism for causing the- Wiping movements of the; plates. For this p-m'pose each. wiper pale-to is provided with a pair of recesses or pin-holes 27 and 28. In Fig, the locking recess 28 0f plate 21, and the reeess 27 of plate 20, are Shown engaged by looking pins later to be do:- seribed, and in Fig. (i the other recesses are soengaiged.

The aotuol plate reversing operation; may he performed by any convenient COT-111%:- tions- I have shown attached beneath each wiper plate a pinion 29, which is engaged by a longitndimilly moving rack 30. For convenience, the melee 31 instead of straight, are shaped alkl. moved along on are, each reek being formed or connected to arm areshapedslide 31. and (H-6h of the two slides provided witl-i an upstanding handle- 32. The handles are located in proximity so that they may be simultw neonel-y grasped to operate both racksand reverses both plates in one motion. Fig. shows the two handles thrown from the operatorto set the wiper plates for a right shoe. and in Fig. 6 the two handles have been pulled toward the opemtor to reverse the plates. As seen in. these figures, and in Fig. 8, the curved slides 31 are separate, so that. if desired, the plates could be independently moved. or relative adjustment might be efieeted. for example, by slipping thin separator between the abutting ends of the slides.

The (*tll'l'fitil Slltlis 31. which earl-y the revei'si eg racks are not fitted directly on the forward exiension 19 of the carrier. but instead are slidablv fitted by means of dovetails on the slides 31. with curved slots formed at 3-1 in segmental Barriers 40. to he later described.

These segmental or curved carriers 40 are also provided with outstanding cars 35, in which are fitted to slide vertically the spring locking pins 36, which engage the locking recesses 27, 28, of the wiper plates, already ieeetioeed. See Fig. 1. The locking pins 36 are pressed yieldingly upwardly so as to normally engage in the locking recesses, but may be drawn downwardly to permit the reversal of the wiper plates by means of an unlocking device or lever 37, one end of which is recessed to engage a groove in the lower end of each locking pin, and the two levers 37 at the two sides being both mounted on a common shaft 38, which may be swung by lifting a convenient handle 39 to depress both locking pins. This permits the handle 32 to be manipulated for reversing the wiper plates. The handle normally rests on a supporting pin 39.

I prefer that the converging or swinging movements of the wiper plates, which take place simultaneously with their advance when acting upon the shoe, shall be a swinging about point F, which is the tip or apex of the contour of the toe, and is also the point at which the contours of the two wiper plates meet. By this mode of swinging the wiping contour around the tip of the toe is maintained continuous throughout the wiping movements and without the need of overlapping the plates.

The members 40, therefore, which directly carry the wiper plates, are fitted to move about the point F as a center, and for this purpose they are constructed of a curved or segmental shape. The vertical pivots 22, about which the wiper plates rotate for their reversing adjustment, are carried directly-at the upper sides of the segmental carriers 40, so that the latter. when moving circularly about the center F, will bodily carry the respective wiper plates toward and from each other with a swinging movement about the same center. As before stated, each segmental carrier also supports the car 35, in which is mounted the wiper plate locking pin, so that, when each plate is adjusted and locked, it is held by the pivot 22 and the locking pin 36 in rigid relation with the carrier.

Each segmental carrier 40 is shown provided with a curved toothed rack 41, by which its movements about the center F may be effected.

In order to guide the segmental carriers in their swinging movements, an upstanding dovetailed guide 42 is mounted directly on the forward extension 19 of the actuating carrier 18. See Figs. 4 and 7. The under sides of the segmental carriers are correspondingly undercut.

Displacement of the wiper plates vertically is prevented by their engagement with the pinions 29, racks 80 and portions of the segmental carriers 40 beneath the plates, while above the wiper plates is securely fastened a cover plate 43, which also substantially incloses and protects the working mechanism. The cover plate 43 is bolted down to the extension 19 by means of bolts 44, two of which serve also as axles for the pinions about to be described.

In order to effectthe swinging movements of the segmental carriers 40 so as to move the wiper plates together and apart,

the racks 41 in said carriers may be engaged, as shown in Figs. 5 and 6, by pinions 45, to which are rigidly secured pinions 46 engaging longitudinal racks 47 at the opposite sides of the head. The racks 47 are sb arranged as not to partake of the longitudinal wiping movements of the head. Therefore, when the carrier 18 is thrust forwardly, advancing the wiper plates and segmental carriers and the pinions 45 and 46, the racks remain stationary, causing the rotation of the pinions, the latter acting upon the curved racks 411 and the segmental carriers to cause the required swinging movements of the latter.

In order to secure the racks '47 to the shell 17, so as to permit relative rotation during the adjustment of lateral tilt, the two racks are shown bolted rigidly to a ring 48, surrounding a convenient portion of the shell 17 and held against longitudinal movement by one or more angle pieces or straps 49.

By the described mechanisms the mere thrusting forwardly and retracting of the longitudinal carrier 18 brings about the complete wiping movements of the wiper plates. A handle 50 may be employed to efi'ect the movements, this being arranged within convenient access, so that the operative may manipulate the handle with the left hand while the right hand takes care of the shoe, and one foot effects the elevation and the lowering of the wiping head by the usual pedal.

The wiping handle 50 is fulcrumed on a floating pivot 51 and is connected by a stem 52 with a head 53, having a swivel engagement with the hollow interior of the carrier 18. The swivel connection permits the carrier to be relatively rotated for adjusting lateral tilt of the head. Upon the handle 50 is shown the usual latch handle 5%, which by means of a latch and the rack 55 is adapted to lock in forward position the carrier 18 and the wiper plates.

The adjustment of lateral tilt may be effected by a hand wheel 56 secured on a threaded shaft 57, passing through threaded ears 58 upstanding from the shell 17. Secured on the shaft 57 between the ears are a pair of lugs 59 adapted to push frontward or rearward a boss 60, which is recessed and loosely surrounds the shaft 57 Downwardly extending from the boss 60 are a pair of arms 61, which partly reach around and have a splined or grasping engagement with longitudinal grooves 62 formed in the carrier 18. By throwing the boss 60 frontward or rearward by means of the handle 56. the carrier 18 is caused to oscillate in either direction, so as to bodily tilt the entire wiping mechanism from a horizontal position in either direction.

A convenient way to alter the longitudim1 tilt is by the mechanism shown in Fig. l, in which, between a leg 63 on the shell 17 and a lug (ii on the bracket 14}, are extended a pair of oppositely threaded bolts 05 engaged. by the oppo itely .tln-eaded sides of the hub of the adjusting hand wheel 66. By turning the hand Wheel in one direction or the other the rear end of the shell 17 is listted or lowered, as des red.

The practical operation of the descrihed machine may be simply that, with the shoe in proper relation to the piping mechanism, the latter is manipulated in the usual manner and b5 the assistance of the handle .50. Assuming that the parts are in the Fig. 5 position, the wiping of the right shoe will thus be completed, at the end of Which the operative will shift the iping hand-ls 50 leftward to retract the wiping mechanism. Before commencing the Wiping operation on the left shoe. the operative with one hand will slightly lift the unlocking handle 39 and then reverse each Wiper plate by simultaneously pulling the handles 32 tonal-d hint; the looking pins 36 alltqlnatieally a tering the ocking recesses in the wiper plates. The wiping handle 50 is then again manipulated for wiping the left shoe. The capability ofquick reversal renders it practical and expedient to perform the lasting of shoes in this advantageous manner, the twoshoes of a pair being lRSted in immediatesnccession, giving superior uniformity in quality and workmanship.

It will thus be seen that I have described a-lasting machine or wiping mechanism embodying the novel principles of the present vantages thereof; and further advantages in the described structure will be apparent to those skilled in the art. Many matters of more design, arrangement, detail or subcombination may be variously modified without departing from the underlying principles of the invention, and, therefore, there is no intention to limit the present invention to such features excepting in so far as the same are recited in the appended claims.
